Three phased burner to significantly reduce gas consumption when not needed

With Navien Condensing, you get not only Great Value but also Condensing Technology and Efficiency. Condensing tankless systems offer substantial savings and contribute to a greener environment. Also, with a Navien Tankless the installation and venting processes are easy, cost effective.

Extended Lifespan

Navien utilizes dual stainless steel heat exchangers, providing a longer life-expectancy and more resistance to erosion. Navien’s stainless steel heat exchangers operate with relatively low water temperatures, minimizing damage from hard water conditions and maintains a high efficiency level. Also, since a condensing tankless is of such high efficiency it produces lower exhaust temperatures, allowing for the use of 3″ PVC venting. This further reduces costs as PVC offers a significant cost savings over other venting materials.
